On April 4, Sens. John Barrasso (R-WY), Orrin Hatch (R-UT) and James Inhofe (R-OK) wrote White House Council on Environmental Quality (CEQ) Chairwoman Nancy Sudley to urge CEQ not to issue guidance that would require federal agencies to consider the greenhouse gas emissions produced outside the United States by American exports when evaluating the environmental impacts of projects. The three senators argued that requiring agencies to do so would set a precedent that could be used to block future American exports.
